    Calcitic shells of the dinoflagellate L. granifera. A) The calcitic shells of L. granifera exhibiting a porous ultrastructure. B) A single shell of L. granifera. C) Raman spectrum from a single shell confirming its calcitic nature. D) Electron back-scattering diffraction (EBSD) map and E) a corresponding (0001) pole figure of a single polished shell demonstrating that it consists of single crystalline domains where the c-axis of calcite is pointing radially from the center of the shell outwards. The colors in (E) correlate with similarly colored areas in (D). Scale bars: (A) 50 µm, (B) 5 µm and (D) is 5 µm.

    Perovskites are materials that are increasingly popular for a wide range of applications because of their remarkable electrical, optical, and photonic properties...
